Just to add:in swahili MEZA =MEZA in Portugues language. 

                                  (samaki)KAMBA = KAMBA portuges etc

Swahili language has  many verbs from the portugues language,and other ethnic  language. Most of the Nouns and adverb and adjectives came from Arab and Persian language which is now dying too,cause Iranin is widely spoken in Iran. 

the example about say a word MAMA is bad example. many languanges in this world they use it eg.Germans,portugues,Turkish lang,russians.Dutch and some part of America eg. Alabama,Arkansas,Tennesse,Kentuckyetc.

so when you give out example please do some reseach before.......Thanks.
